ideally it could be sent as cleanup patch up-front (then it can be applied even
if the rest needs another round ;)) or at least mentioned somewhere (e.g., in
the patch notes). seemingly unrelated changes in a patch always make me wary that
the patch was generated from some unclean tree/more or less than intended was
`git add`ed. in this case my guess was that you just changed that (wrapped) call
site to match your newly introduced ones, but it could also have been an
unintentional search+replace result, for example, so I'd rather ask :)
